Introduction
Phoenix is a modern web framework built on Elixir that emphasizes performance, concurrency, and realtime capabilities. It provides a robust structure and toolchain for taking applications from prototype to production.
Key Features
- High concurrency and low latency leveraging the Erlang/OTP platform
- Built-in realtime primitives (Channels / LiveView)
- Powerful routing and request pipeline
- Generators and developer tooling for fast iteration
Use Cases
- Realtime collaboration apps (chat, whiteboard, collaborative editing)
- High-concurrency API services and microservices
- Low-latency backends for finance or IoT
- Education, social, and communication products
Technical Highlights
- Fault-tolerant and hot-upgrade capable via the Erlang VM
- LiveView for server-rendered realtime UIs
- Mature ecosystem (Hex packages, detailed docs)
